Characteristics of Yuan blue and white glaze

The Yuan Dynasty began to use the dual-mixing method of high-quality porcelain clay from the Kaoling Mountains and porcelain stone to configure the porcelain body. The quality of the glaze has become more vitrified than that of the Song Dynasty Yingqing. The level is much higher, solid and delicate, but still contains metal impurities, so after firing, there are many blisters, brush marks and iron spots on the sand bottom, and red spots appear on the bottom, mouth edge and shrinkage glaze, commonly known as " Flint Red”.

Yuan blue and white vessels are generally large and clumsy, and their bodies are thicker and heavier than porcelain of other eras. The tire repair is also not very precise. The joints of large cans and bottles are not carefully cut, and they are uneven when touched by hand. In addition, it is not easy to bake large vessels, so defects such as warped edges, flattening, concave centers, and collapsed bottoms are inevitable. .

The glaze color of Yuan blue and white is generally bluish-white, and it is bluish in the early stage. The glaze is thicker and often has tear marks, and the color of the tear marks is more bluish gray. The late ones, especially the Zhengzheng fine ones, have a suitable glaze thickness and a translucent glaze color that is almost white. The glaze applied on the vessel is sparse and thin, making the joint marks more obvious.
